Saving your eyes on Linux

Posted: December 30, 2011 in Uncategorized

I found what may be one of the greatest programs ever written…. It’s called RedShift. Basically, it allows you to change the color temperature of your monitor, essentially modifying the colors to make them more red or blue. This gives a good explanation:

My Mom recently had a problem on her computer. Micro$oft Word showed a file in her recent documents, but trying to search for it in OS X failed to show anything.

So, I did a bit of searching (I use Linux, so the commands are the same in OS X… .at least the basic ones), and found out about the “find” command. It searches your computer essentially.

So, if you can’t find a file on your computer running a UNIX based OS, follow this tutorial. But, add the “sudo ” command before the “find / -name NAME” command.

Cool philanthropy project

So, I had a cool idea. I don’t know if my Mom will let me do it, however. So, I have the old iBook G4. Honestly, I don’t need it, I think someone else could use it. So, what I was thinking of doing was taking it, wiping everything off of it, then doing an install of Arch Linux PPC on it, and set it up perfectly, to work perfectly. Because the wifi card is broken, I will buy a USB wifi adapter, there’s no webcam so I will buy one of those for it. I have some RAM laying around that may work in it, so I’ll put a gig in it, and, of course, give it a full KDE desktop. I will even write a quick instruction manual about it, and make a DVD that will play in the computer on using the system. And, of course, I will include an image of the system after I am done building it, and a Clonezilla disk to restore it to it’s original state if the need arises.

Then, I will figure out a way to get the computer to a student (preferably beginning high school, as they will get the most use out of it) who needs a computer, but can’t afford one.

I’m on vacation right now, but I just had to write about this.
So, every Sunday morning, I get up and listen to the Linux Action Show. It’s really entertaining, I love listening to it, very informative. So, the latest episode was a review of the AROS Reasearch Operating System, which is basically an open source re-implementation of the Amiga OS. It looks like a great OS for putting on old macs, as it works on PPC, in addition to x86.

I am interested in porting FreeBSD’s Linux compatibility layer over to it. Does anyone have any experience with this, or GDB (GNU Debugger)

It’s a problem that I’ve faced many times before: KNetworkManager hangs at “setting network address”.

For some reason, so many wifi networks have a weird setup that causes this. Well, through internet research, I’ve found the solution. And it’s simple as hell.

This only applies if the network uses WEP encryption. Otherwise, I can’t help you.

It seems that many networks use a 64-bit key. I guess it’s for backwards compatibility.

When you have the network edit thing open:

Go to the “Wireless Security” tab.

Now click on the little thing next to “Key type”.

And click on “Hex or Ascii Key (for 64 or 128 bit)” Enter in the wifi password. Click “Ok”. Then, apply (I think), and re-click on the network from the Knetworkmanager applet.It should work. It did for me.

Chakra GNU/Linux

Posted: June 24, 2011 in Uncategorized

I installed Chakra GNU/Linux on my HP laptop. It’s really great distribution, however, it’s not stable AT ALL! It’s very crashy, however, it’s still in the alpha stage (on the installer it says “THIS IS ALPHA SOFTWARE, IT COULD EAT YOUR HAMSTER”), so that’s expected. I think it has a lot of potential, however, until it comes out of Alpha and becomes more mature, I’m going to just do an install of Arch or Pardus.

Calculus is awesome!

Okay, so my skills in Calculus are improving dramatically. I am getting good with integrals. Actually, I’m in precalculus, and sometimes I will take equations given to us in class, find the derivative, and then try to find the integral of that derivative. One of the coolest things has been applying it to physics.
Take a rocket. Let’s just say for simplicity, it’s in space, and the rocket engines haven’t been deployed yet. It is not moving. Then, all of a sudden, the engines begin to deploy. As more and more fuel ignites, the acceleration of the rocket increases. This happens for thirty seconds, until the acceleration becomes level, at the maximum that it can be. For twenty more seconds, it stays level at 500 m/s^2. Then, the rocket engines start to run out of fuel, and it the acceleration drops from 500 m/s^2 to zero in a time of twenty-five seconds. Find the distance that the rocket traveled in the seventy five seconds the rocket engines were on.

What I did was draw a sketch of the time vs acceleration graph, and the time vs. velocity graph. The time vs. acceleration graph looks like a trapezoid. The time vs. velocity graph curves up as acceleration increases looking like a y = x^2 graph, then is a straight up, like a y = x graph, when acceleration flatlines, and then curving up again as acceleration decreases, looking like a y = x^(1/2) graph.

Then, I just split it up each part of the acceleration graph.

I will finish this post later
